On the basis of drop down patterns found in the scene of fire, a study on burn pattern was made through simulation with model, test of deformation due to radiant heat, and ignition test regarding an effect produced on the scene of fire. And the results of study led to the following conclusions. First, in the ignition test of thermoplastic film, it was possible to verify that trash bag and greenhouse film has the largest amount of debris and the fallen debris had kept reburning for a long period of time. Among test materials, wrap had a high burning rate, and instantaneously burned. And in case there was a combustible at the end of burning, it was possible to verify that burning could extend. Second, in the radiant heat test on the upper part [temperature 340℃(±5℃)] of heating element in electric stove, it was possible to verify that all of 3 types except wrap ignited and debris flew down. Third, it was possible to verify that radiant heat and convective heat formed the temperature which could ignite a thermoplastic film through FDS and full-scale model. And it was verified that convection current can ignite a thermoplastic film. As a result, it was possible to find that an independent ignition point occurred. In the future, the results of this study are expected to become small reference data in scene investigation. And it is to be hoped that the results of this study will provide an opportunity for fire station to win the public trust outside as a professional fire cause investigation organization, and to contribute to the improvement of credibility by the scientific determination of fire cause.
